  At present, there are many small saw mills on the market, hand workshops; grinding saw blade is only on the front corner of the sawtooth, simple and rough processing, after processing has changed the original angle of the saw blade, the back angle of the saw blade , Side angles, and tooth chambers have no treatment at all, and they are not calibrated after grinding.


  The following describes my grinding process and inspection process, and related technical standards. I hope to help you.


  A. After grinding the saw blade, first, all saw blades are soaked in warm water at 50 degrees Celsius for 30 minutes, then cleaned, rusted, and processed for initial visual inspection.


  B. Then use the angle table to check the angle, including the detection of the rake angle, back angle and side angle of the tooth (see if there are cracks, missing corners, etc.), then zoom in on the precision projector by 50~100 times to determine The original angle of the sawtooth and the wear condition of the saw blade, such as the smaller angle of the teeth, can be used to increase the amount of grinding to reduce the grinding cost of the customer (in principle, my basic amount of grinding is to take ten serrations each time).


  C. If there are carbide teeth (tungsten steel cutter head) need to be replaced, then the German KAHNY automatic welding machine for tooth exchange operations.


  D. The next step is to perform stress correction of the saw blade. This step is a critical process for saw blade grinding services. At present, at least 95% of the domestic grinding manufacturers cannot perform stress correction and need to have very rich experience. Senior engineer to complete the saw blade in the process of high-speed operation, under the action of external forces, the saw blade's stress has changed, the saw blade's side accuracy has a large deflection, so there will be larger saw road, rough surface Large burr, etc., stress adjustment is required to be more than 2 times, if you can adjust to the standard range (this standard refers to the Japanese saw blade production standards, that is, the side of the saw blade accuracy), then enter the next A process; on the other hand, if grinding is required, perform the best efforts to correct and precision grinding again, and use the idea! Saw blade grinding is performed in two batches. First, coarse grinding is performed using a 200-grit Japanese imported diamond grinding wheel, and then 600-grit grinding wheel is used for more precise grinding.


  E. The next step is to check the vibration rate. The qualified saw blade will be further processed according to the step B. The final inspection will be performed. After it is fully qualified, it will be placed in the waiting delivery area. The worksheet will be handed over to the business to complete the entire grinding process.


  Of course, this standard cannot be achieved in the general grinding process, so it can only be operated by its own visual inspection and senses.
